10 Best Cordless Angle Grinders 2025 in the United States

The Milwaukee 2880-20 M18 FUEL Cordless Angle Grinder is a well-rounded tool designed for various grinding tasks, making it a solid choice for both DIY enthusiasts and professionals. With its brushless motor, this grinder offers an impressive no-load speed of up to 8,500 RPM, ensuring efficiency in cutting and grinding applications. It operates on an 18V battery, which is compatible with all M18 batteries, providing flexibility for users who already own Milwaukee tools.

One of the standout features is the Electronic Clutch that protects against kickback, enhancing user safety during operation. Additionally, it includes overload protection to extend the motor's life, making it a reliable investment over time. The anti-vibration side handle is another plus, contributing to user comfort, especially during prolonged use.

However, there are a couple of considerations. The grinder is sold as a tool only, meaning you will need to purchase the battery separately if you don’t already have one. This can add to the initial cost for new users. Also, while it is relatively lightweight at around 5 pounds, some users may still find it a bit bulky for extended overhead work. In terms of ergonomics, its compact design helps, but users looking for a more maneuverable option may want to try out other models. The 5-year warranty is a reassuring factor, indicating Milwaukee's confidence in the product's durability.

The Makita XAG04Z 18V LXT® Lithium-Ion Brushless Cordless Angle Grinder is a solid choice for users looking for a dependable and efficient tool. One of its standout features is the BL Brushless Motor, which eliminates carbon brushes, allowing the motor to run cooler and more efficiently, thereby extending its lifespan. This grinder also offers Automatic Speed Change technology, which adjusts the speed and torque during use to maintain optimum performance, and Active Feedback-sensing Technology (AFT) that turns off the motor if the wheel's rotation is suddenly forced to stop, enhancing safety.

The no-load speed of 8500 RPM is suitable for a range of applications. It accommodates disc sizes of 4-1/2” and 5”, offering flexibility depending on the job requirements. With a weight of 4.8 pounds, it strikes a good balance between sturdiness and ease of handling. Users will appreciate the ergonomics, as the tool is designed to be comfortable for extended use.

However, it's important to note that the product does not include batteries, which means an additional purchase is necessary if you don't already own compatible batteries. Additionally, beginners might find the need for buying separate batteries and chargers a bit inconvenient. Its robust safety features, efficient motor, and high performance make it a reliable option for both professional and DIY users.

The Milwaukee 2686-20 18V Cordless Angle Grinder is a robust tool suitable for those who need mobility and power in their grinding tasks. Its 18V battery offers a good balance between power and portability, though the actual battery capacity (Ah) is not specified, which might affect the runtime depending on the battery you use. This grinder supports both 4.5” and 5” discs, which provides flexibility for various grinding applications. With a no-load speed of 11,000 RPM, it is quite fast and efficient for most cutting and grinding tasks.

Weighing 1.6 kilograms, it is relatively lightweight, making it easier to handle and reducing user fatigue during extended use. The paddle switch design ensures better control and safety, while the tool-free guard adjustment simplifies the process of changing the guard, enhancing convenience. The overload protection and electronic clutch are valuable safety features that protect both the user and the tool from damage.

It is worth noting that this model is sold as a 'tool-only' version, meaning you will need to purchase the battery and charger separately if you don't already own them. Additionally, it does not mention having a brushless motor, which typically offers better efficiency and longevity. This angle grinder is a solid choice for DIY enthusiasts and professionals who value power, safety, and the convenience of a cordless tool.
